Nine years and counting: The underground mapping project that won’t quit
A long-running project to map the city’s underground infrastructure has faced years of delays and rising costs. Originally expected to take just two to three years, the effort is now in its ninth year. Officials remain hopeful that the final map will improve emergency response and public safety once completed.
The initiative began with a $10 million federal grant, overseen by the Mayor’s Office of Operations. Its goal was to create a detailed digital map of everything beneath the streets—water lines, electrical conduits, and gas pipelines. But progress stalled as crews repeatedly uncovered uncharted utilities during excavation.
The city’s deputy commissioner of infrastructure admitted that these unexpected discoveries caused major setbacks. Each new find required additional surveys, redesigns, and approvals, stretching timelines and budgets far beyond early estimates. Despite the challenges, project lead Dan Steinberg has emphasised the map’s future benefits. He believes it will cut emergency response times by giving crews precise underground data. The city now plans to launch the mapping platform in early 2028.
The project has already consumed far more time and money than anticipated. If successful, the underground map will provide critical information for first responders and construction teams. Officials have not yet announced whether further delays could push the launch date beyond 2028.
